Well I picked up my new (to me) XC dually - a Jamis Dakar XC Comp.
I wanted a dually but not a downhill one - unlike some of you guys I still want to pedal
Gees it's a nice bike to ride, really light and nimble - now I don't want to stuff the handling *too* much, say by adding a 3 or 4kg wheel and 4kgs of battery...oh well..
So I have my nominal 250w front hub motor from my old bike.
I was planning to:
- Machine holes in side plate of motor to fit 203mm disc. And machine/buy adapter for the caliper. (Or buy a new side plate if I can.) A 203 mm disc will clear the motor. I'll need to keep the bolts near the centre of the disc to let it flex as the brake actuates - they only move on one side.
- Weld up torque bars from Brett onto stiffening "sheaths" on the lower legs of the Triple Clamp forks. Sheaths are clamped to the fork leg with hose clampts, and with preload holding the motor against the rear of the dropout. I don't want to stuff the stock Mantitou Black Elite forks and I don't like the way the Staunchions fit into the crown anyway- they've gone for light weight.
- Either keep going with battery in backpack (handles better) or go with a Beam rack mount at the rear, really close to the seat, and as low as possible to clear the rear wheel as it moves. Unfortunately the battery won't fit in the frame triangle.
- I also picked up a heavy duty Pivot dual wall 36 spoke rim for $10. To fit to the motor some day - no more bent rims for me
But some advice please? Should I stick with a front hub motor? Go rear (but I'd need to fit a nine gear cluster and a disc...)?
Cheers
